Re: A bad CRT in 465?
Be very sure what is riding on the filaments voltage. In some Tek get the -HV supply DC is on the filaments. I think it is this way is some of the 7K frames and I am sure it is this way on the 576. You also don’t want to turn the bonding wires in to a fuse that will make the tube terminal for sure.toggle quoted messageShow quoted text

So I'm thinking after reading a few CRT rejuvenation links that I may put 6.3 volts DC or maybe a little more on the filament. And tie the grid to the cathode. Sort of a quick and easy attempt at bringing the tube back to life.
Nothing really to lose here and pretty safe I think.
